    摘要： This invention comprises a process for generating particles of MAg4I5, wherein M is a monovalent cation, which comprises dissolving AgI and MI in a polar solvent followed by precipitating particles of MAg4I5 by adding the solution to a nonpolar solvent. The resulting MAg4I5 is in the form of anisotropic crystalline particles. The MAg4I5 particles can be used in the preparation of a photothermographic element. The invention also comprises method of preparing a stable aqueous emulsion of MAg4I5 particles.

    摘要： A process of preparing a radiation-sensitive silver halide emulsion is disclosed in which a polyalkylene oxide block copolymer surfactant is employed. Dispersion of the polyalkylene oxide block copolymer surfactant in the aqueous dispersing medium is increased by the inclusion of an auxiliary surfactant. The auxiliary surfactants are selected from among those that, in the form of an aqueous solution containing 10 percent by weight of the auxiliary surfactant based on total weight of the aqueous solution, is miscible in all proportions with at least one of water and the polyalkylene oxide block copolymer surfactant.
